Q235B Elliptical Heads DIsh Heads Tank Caps For Heat Exchanger Parts

We supply a variety of dish heads types such as Semi Elliptical, Torispherical, Hemi Head , Dished Head, Flat and Ellipsoidal Head.

Dish Heads also known as dished ends or tank heads are an important component of pressure vessels.

There is a multitude of types and sizes of dished heads used in different industries. These dished heads are handled in various methods such as deep drawing, cold forming, spinning, dishing, and flanging, as well as forming the heads in crown and petal segments.

The elliptical head ( or named ellipsoidal head ) which is a head consisting of two parts: a rotating ellipsoidal sphere and a cylindrical straight section. Elliptical tank head is fabricated to have a certain shape instead of a particular dish radius or knuckle radius. The dish radius is approximately 90% of the diameter and the knuckle radius is approximately 17% of the diameter. 2:1 elliptical flanged and dished heads are ASME compliant.
